I'm getting ready to install Exchange 2010 SP3 and UR11. In this environment we have: 2 CAS/HUB servers 2 Mailbox servers 1 CAS/HUB/Mailbox server
The DAG consists of information stores on the 2 mailbox servers and the CAS/HUB/Mailbox server. I know I should begin updating the CAS/HUB servers first and then the Mailbox. But in the case of having a CAS/HUX/Mailbox in the mix, do I save it for last or do it first, or does it matter? -Paul
